BACKGROUND

Embodiments herein relate to compounds and methods for the treatment of RAS-mediated disease. In particular, embodiments herein relate to compounds and methods for treating diseases such as cancer via targeting oncogenic mutants of the K-RAS isoform.

Ras proteins are small guanine nucleotide-binding proteins that act as molecular switches by cycling between active GTP-bound and inactive GDP-bound conformations. Ras signaling is regulated through a balance between activation by guanine nucleotide exchange factors (GEFs), most commonly son of sevenless (SOS), and inactivation by GTPase-activating proteins (GAPs) such as neurofibromin or p120GAP. The Ras proteins play an important role in the regulation of cell proliferation, differentiation, and survival. Dysregulation of the Ras signaling pathway is almost invariably associated with disease. Hyper-activating somatic mutations in Ras are among the most common lesions found in human cancer. Most of these mutations have been shown to decrease the sensitivity of Ras to GAP stimulation and decrease its intrinsic GTPase activity, leading to an increase in the active GTP-bound population. Although mutation of any one of the three Ras isoforms (K-Ras, N-Ras, or H-Ras) has been shown to lead to oncogenic transformation, K-Ras mutations are by far the most common in human cancer. For example, K-Ras mutations are known to be often associated with pancreatic, colorectal and non-small-cell lung carcinomas. Similarly, H-Ras mutations are common in cancers such as papillary thyroid cancer, lung cancers and skin cancers. Finally, N-Ras mutations occur frequently in hepatocellular carcinoma.

There is a need for effective Ras inhibitors, which may provide a new class of anticancer compounds. These and other advantages will be apparent to those skilled in the art based upon embodiments and disclosures herein.

In embodiments of the invention, any one of the positions that is understood to have a hydrogen may also exist or understood to be isotopically enriched. In the compounds of this invention any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Obtaining 100% deuteration at any relevant site of a compound in an amount of milligram or greater can be difficult. Therefore, it is understood that some percentage of hydrogen may still be present, even though a deuterium atom is specifically shown in a chemical structure. Thus, when a chemical structure contains a “D,” the compound represented by the structure is deuterium-enriched at the site represented by “D.” Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen,” the position is understood to have hydrogen at its natural abundance isotopic composition. Also unless otherwise stated, when a position is designated specifically as “D” or “deuterium,” the position is understood to have deuterium at an abundance that is at least 3340 times greater than the natural abundance of deuterium, which is 0.015% (i.e., the term “D” or “deuterium” indicates at least 50.1% incorporation of deuterium). In embodiments, a benzene ring may be optionally exist as —C₆D₅, —C₆DH₄, —C₆D₂H₃, —C₆D₃H₂, and —C₆D₄H. In embodiments, a cyclohexyl group may optionally exist as —C₆D₁₁.

Any definition herein may be used in combination with any other definition to describe a composite structural group. By convention, the trailing element of any such definition is that which attaches to the parent moiety. For example, the composite group alkylamido would represent an alkyl group attached to the parent molecule through an amido group, and the term alkoxyalkyl would represent an alkoxy group attached to the parent molecule through an alkyl group.

When a group is defined to be “null,” what is meant is that said group is absent. A “null” group occurring between two other group may also be understood to be a collapsing of flanking groups. For example, if in —(CH₂)_(x)G¹G²G³, the element G² were null, said group would become —(CH₂)_(x)G¹G³.

The term “optionally substituted” means the anteceding group or groups may be substituted or unsubstituted. Groups constituting optional substitution may themselves be optionally substituted. For example, where an alkyl group is embraced by an optional substitution, that alkyl group itself may also be optionally substituted. When substituted, the substituents of an “optionally substituted” group may include, without limitation, one or more substituents independently selected from the following groups or a particular designated set of groups, alone or in combination: alkyl, alkenyl, alkynyl, alkanoyl, heteroalkyl, heterocycloalkyl, haloalkyl, haloalkenyl, haloalkynyl, lower perhaloalkyl, perhaloalkoxy, cycloalkyl, phenyl, aryl, aryloxy, alkoxy, haloalkoxy, oxo, acyloxy, carbonyl, carboxyl, alkylcarbonyl, carboxyester, carboxamido, cyano, hydrogen, halogen, hydroxy, amino, alkylamino, arylamino, amido, nitro, thiol, alkylthio, haloalkylthio, perhaloalkylthio, arylthio, sulfonate, sulfonic acid, trisubstituted silyl, N₃, SH, SCH₃, C(O)CH₃, CO₂CH₃, CO₂H, pyridinyl, thiophene, furanyl, carbamate, and urea. Particular subsets of optional substitution include, without limitation: (1) alkyl, halo, and alkoxy; (2) alkyl and halo; (3) alkyl and alkoxy; (4) alkyl, aryl, and heteroaryl; (5) halo and alkoxy; and (6) hydroxyl, alkyl, halo, alkoxy, and cyano. Where an optional substitution comprises a heteroatom-hydrogen bond (—NH—, SH, OH), further optional substitution of the heteroatom hydrogen is contemplated and includes, without limitation optional substitution with alkyl, acyl, alkoxymethyl, alkoxyethyl, arylsulfonyl, alkyl sulfonyl, any of which are further optionally substituted. These subsets of optional substitutions are intended to be merely exemplary and any combination of 2 to 5, or 2 to 10, or 2 to 20 of the groups recited above up to all the group recited above and any subrange in between are contemplated. “Optionally substituted” may include any of the chemical functional groups defined hereinabove and throughout this disclosure. Two optional substituents may be joined together to form a fused five-, six-, or seven-membered carbocyclic or heterocyclic ring consisting of zero to three heteroatoms, for example forming methylenedioxy or ethylenedioxy. An optionally substituted group may be unsubstituted (e.g., —CH₂CH₃), fully substituted (e.g., —CF₂CF₃), monosubstituted (e.g., —CH₂CH₂F) or substituted at a level anywhere in-between fully substituted and monosubstituted (e.g., —CH₂CF₃).

The various optional substitutions need not be the same and any combination of optional substituent groups may be combined. For example, a carbon chain may be substituted with an alkyl group, a halo group, and an alkoxy group. Where substituents are recited without qualification as to substitution, both substituted and unsubstituted forms are encompassed. Where a substituent is qualified as “substituted,” the substituted form is specifically intended. Additionally, different sets of optional substituents to a particular moiety may be defined as needed; in these cases, the optional substitution will be as defined, often immediately following the phrase, “optionally substituted with.”

The term R or the term R′, appearing by itself and without a number designation, unless otherwise defined, refers to a moiety selected from the group consisting of hydrogen, hydroxyl, halogen, alkyl, cycloalkyl, heteroalkyl, aryl, heteroaryl and heterocycloalkyl, any of which may be optionally substituted. Each such R and R′ groups should be understood to be optionally substituted as defined herein. Each incidence of R and R′ should be understood to be independent. Whether an R group has a number designation or not, every R group, including R, R′ and R^(n) where n=(1, 2, 3, . . . n), every substituent, and every term should be understood to be independent of every other in terms of selection from a group. Should any variable, substituent, or term (e.g. aryl, heterocycle, R, etc.) occur more than one time in a formula or generic structure, its definition at each occurrence is independent of the definition at every other occurrence. Those of skill in the art will further recognize that certain groups may be attached to a parent molecule or may occupy a position in a chain of elements from either end as written. Thus, by way of example only, an unsymmetrical group such as —C(O)N(R)— may be attached to the parent moiety at either the carbon or the nitrogen.

Asymmetric centers, axial asymmetry (non-interchanging rotamers), or the like may exist in the compounds of the various embodiments disclosed herein. Such chirality may be designated by the symbols “R” or “S,” depending on the configuration of substituents around the chiral carbon atom or the relevant axis. It should be understood that embodiments encompasses all stereochemical isomeric forms, including diastereomeric, enantiomeric, and epimeric forms, d-isomers and 1-isomers, and mixtures thereof. Individual stereoisomers of compounds can be prepared synthetically from commercially available starting materials which contain chiral centers or by preparation of mixtures of enantiomeric products followed by separation such as conversion to a mixture of diastereomers followed by separation or recrystallization, chromatographic techniques, direct separation of enantiomers on chiral chromatographic columns, or any other appropriate method known in the art. Starting compounds of particular stereochemistry are either commercially available or can be made and resolved by techniques known in the art. Additionally, the compounds of the various embodiments disclosed herein may exist as geometric isomers. The various embodiments disclosed herein includes all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof.

The term “bond” refers to a covalent linkage between two atoms, or two moieties when the atoms joined by the bond are considered part of larger substructure. A bond may be single, double, or triple unless otherwise specified. A dashed line between two atoms in a drawing of a molecule indicates that an additional bond may be present or absent at that position.

Compounds described herein have the ability penetrate the CNS in order to treat CNS cancers, both primary and metastatic. Also, the treatments can include treating a cancer originated in the CNS that metastasizes to other parts of the CNS or outside of the CNS. Thus, compounds disclosed herein can also prevent or reduce metastatic pathways via the CNS.

“Ras associated cancer” (also referred to herein as “Ras related cancer”) refers to a cancer caused by aberrant Ras activity or signaling. A “cancer associated with aberrant K-Ras activity” (also referred to herein as “K-Ras related cancer”) is a cancer caused by aberrant K-Ras activity or signaling (e.g. a mutant K-Ras). K-Ras related cancers may include lung cancer, non-small cell lung cancer, breast cancer, leukemia, pancreatic cancer, colon cancer, colorectal cancer. Other cancers that are associated with aberrant activity of one or more of Ras, K-Ras, H-Ras, N-Ras, mutant K-Ras (including K-Ras G12C, K-Ras G12V, K-Ras G13C, K-Ras G12D, K-Ras G13D mutants), mutant N-Ras, and mutant H-Ras are well known in the art, including G12C in both N-Ras and H-Ras, and determining such cancers are within the skill of a person of skill in the art.

The term “administer (or administering) a Ras inhibitor” means administering a compound that inhibits the activity or level (e.g. amount) or level of a signaling pathway of one or more Ras proteins (e.g. a Ras inhibitor, K-Ras inhibitor, N-Ras inhibitor, H-Ras inhibitor, mutant K-Ras inhibitor, K-Ras G12C inhibitor, K-Ras G12V inhibitor, K-Ras G13C inhibitor, K-Ras G12D inhibitor, K-Ras G13D inhibitor) to a subject. Administration may include, without being limited by mechanism, allowing sufficient time for the Ras inhibitor to reduce the activity of one or more Ras proteins or for the Ras inhibitor to reduce one or more symptoms of a disease (e.g. cancer, wherein the Ras inhibitor may arrest the cell cycle, slow the cell cycle, reduce DNA replication, reduce cell replication, reduce cell growth, reduce metastasis, or cause cell death). The term “administer (or administering) a K-Ras inhibitor” means administering a compound that inhibits the activity or level (e.g. amount) or level of a signaling pathway of one or more K-Ras proteins (K-Ras, mutant K-Ras, K-Ras G12C, K-Ras G12V, K-Ras G12D, K-Ras G13C, K-Ras G13D). In embodiments, the administering does not include administration of any active agent other than the recited active agent.

The term “associated” or “associated with” in the context of a substance or substance activity or function associated with a disease (e.g. Ras (e.g., human K-Ras or human H-Ras) activity, a protein associated disease, a cancer associated with aberrant Ras activity, K-Ras associated cancer, mutant K-Ras associated cancer, activated K-Ras associated cancer, K-RasG12C associated cancer, K-Ras G12V associated cancer, K-Ras G13C associated cancer, K-Ras G12D associated cancer, K-Ras G13D associated cancer) means that the disease (e.g. cancer) is caused by (in whole or in part), or a symptom of the disease is caused by (in whole or inpart) the substance or substance activity or function. For example, a cancer associated with aberrant Ras activity or function may be a cancer that results (entirely or partially) from aberrant Ras activity or function (e.g. enzyme activity, protein-protein binding, signaling pathway) or a cancer wherein a particular symptom of the disease is caused (entirely or partially) by aberrant Ras activity or function. As used herein, what is described as being associated with a disease, if a causative agent, could be a target for treatment of the disease. For example, a cancer associated with aberrant Ras activity or function or a Ras associated cancer, may be treated with a Ras modulator or Ras inhibitor, in the instance where increased Ras activity or function (e.g., signaling pathway activity) causes the cancer. For example, a cancer associated with K-Ras G12C may be a cancer that a subject with K-Ras G12C is at higher risk of developing as compared to a subject without K-Ras G12C. For example, a cancer associated with K-Ras G12V may be a cancer that a subject with K-Ras G12V is at higher risk of developing as compared to a subject without K-Ras G12V.

The term “Ras” refers to one or more of the family of human Ras GTPase proteins (e.g. K-Ras, H-Ras, N-Ras). The term “K-Ras” refers to the nucleotide sequences or proteins of human K-Ras (e.g. human K-Ras4A (NP 203524.1), human K-Ras4B (NP 004976.2), or both K-Ras4A and K-Ras4B). The term “K-Ras” includes both the wild-type form of the nucleotide sequences or proteins as well as any mutants thereof. In some embodiments, “K-Ras” is wild-type K-Ras. In some embodiments, “K-Ras” is one or more mutant forms. The term “K-Ras” XYZ refers to a nucleotide sequence or protein of a mutant K-Ras wherein the Y numbered amino acid of K-Ras that has an X amino acid in the wildtype instead has a Z amino acid in the mutant (e.g. K-Ras G12C has a Gin wildtype protein but a C in the K-Ras G12C mutantprotein). In some embodiments K-Ras refers to K-Ras4A and K-Ras4B. In some embodiments, K-Ras refers to K-Ras4A. In some embodiments, K-Ras refers to K-Ras4B (e.g., NM 004985.4 or NP 004976.2). In some embodiments, K-Ras refers to the protein including (e.g., consisting of) the amino acid sequence below or including the sequence below with one or more mutations (e.g., G12C, G12V, or G13C):

The term “combination therapy” means the administration of two or more therapeutic agents to treat a therapeutic condition or disorder described in the present disclosure. Such administration encompasses co-administration of these therapeutic agents in a substantially simultaneous manner, such as in a single capsule having a fixed ratio of active ingredients or in multiple, separate capsules for each active ingredient. In addition, such administration also encompasses use of each type of therapeutic agent in a sequential manner. In either case, the treatment regimen will provide beneficial effects of the drug combination in treating the conditions or disorders described herein.

“K-RAS inhibitor” is used herein to refer to a compound that exhibits an IC₅₀ with respect to K-RAS activity of no more than about 100 mM and more typically not more than about 50 mM, as measured in the K-RAS assay described generally hereinbelow. “IC₅₀” is that concentration of inhibitor that reduces the activity of an enzyme (e.g., K-RAS) to half-maximal level. Compounds of the various embodiments disclosed herein have been discovered to exhibit inhibition against oncogenic mutant K-RAS isoforms. In some embodiments, compounds will exhibit an IC₅₀ with respect to oncogenic mutant K-RAS of no more than about 10 mM; in further embodiments, compounds will exhibit an IC₅₀ with respect to K-RAS of no more than about 5 mM; in yet further embodiments, compounds will exhibit an IC₅₀ with respect to K-RAS of not more than about 1 mM, as measured in the K-RAS assay described herein. In yet further embodiments, compounds will exhibit an IC₅₀ with respect to K-RAS of not more than about 200 nM. Without being bound by theory, in some embodiments, the K-RAS inhibitor is an irreversible inhibitor by way of covalent bond formation to the cysteine at the G12C mutation site.

The phrase “therapeutically effective” is intended to qualify the amount of active ingredients used in the treatment of a disease or disorder. This amount will achieve the goal of reducing or eliminating the the disease or disorder.

As used herein, reference to “treatment” of a subject is intended to include prophylaxis. The term “subject” means all mammals, including humans. Examples of subjects include humans, cows, dogs, cats, goats, sheep, pigs, and rabbits. In some embodiments, the subject is a human.

The term “prodrug” refers to a compound that is made active in vivo through chemical reaction in vivo thereby releasing an active compound. Compounds disclosed herein can be modified to exist as prodrugs, as described in Hydrolysis in Drug and Prodrug Metabolism: Chemistry, Biochemistry, and Enzymology (Testa, Bernard and Mayer, Joachim M. Wiley-VHCA, Zurich, Switzerland 2003). Prodrugs of the compounds described herein are structurally modified forms of the compound that readily undergo chemical changes under physiological conditions to provide the active compound. Additionally, prodrugs can be converted to the active compounds by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to a compound when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent. Prodrugs are often useful because, in some situations, they may be easier to administer than the active compound, or parent drug. They may, for instance, be bioavailable by oral administration whereas the parent drug is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. A wide variety of prodrug derivatives are known in the art, such as those that rely on hydrolytic cleavage or oxidative activation of the prodrug. An example, without limitation, of a prodrug is a compound which is administered as an ester (the “prodrug”), which is then metabolically hydrolyzed to the carboxylic acid, as the active entity. Additional examples include peptidyl derivatives of a compound. The term “therapeutically acceptable prodrug,” refers to those prodrugs or zwitterions which are suitable for use in contact with the tissues of subjects without undue toxicity, irritation, and allergic response, are commensurate with a reasonable benefit/risk ratio, and are effective for their intended use.

The pharmaceutical composition may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. Typically, these methods include the step of bringing into association a compound disclosed herein or a pharmaceutically acceptable salt, ester, amide, prodrug or solvate thereof (“active ingredient”) with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers or both and then, if necessary, shaping the product into the desired formulation.

Pharmaceutical compositions of the various embodiments disclosed herein suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be presented as a bolus, electuary or paste.

Pharmaceutical compositions that can be used orally include tablets, push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with binders, inert diluents, or lubricating, surface active or dispersing agents. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated to provide slow or controlled release of the active ingredient therein. All formulations for oral administration should be in dosages suitable for such administration.

The compounds disclosed herein may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in powder form or in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, saline or sterile pyrogen-free water, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

Formulations for parenteral administration include aqueous and non-aqueous (oily) sterile injection solutions of the active compounds which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.

The second agent of the pharmaceutical combination formulation or dosing regimen may have complementary activities to the compounds disclosed herein such that they do not adversely affect each other. The compounds may be administered together in a unitary pharmaceutical composition or separately. In one embodiment a compound or a pharmaceutically acceptable salt can be co-administered with a cytotoxic agent to treat proliferative diseases and cancer.

The term “co-administering” refers to either simultaneous administration, or any manner of separate sequential administration, of a compound disclosed herein or a salt thereof, and a further active pharmaceutical ingredient or ingredients, including cytotoxic agents and radiation treatment. If the administration is not simultaneous, the compounds are administered in a close time proximity to each other. Furthermore, it does not matter if the compounds are administered in the same dosage form, e.g. one compound may be administered topically and another compound may be administered orally.

Those additional agents may be administered separately from an inventive compound-containing composition, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.

In certain embodiments, compositions of this invention are formulated such that a dosage of between 0.01-100 mg/kg body weight/day of an inventive can be administered.

Typically, any agent that has activity against a disease or condition being treated may be co-administered. Examples of such agents can be found in Cancer Principles and Practice of Oncology by V. T. Devita and S. Hellman (editors), 6^(th) edition (Feb. 15, 2001), Lippincott Williams & Wilkins Publishers. A person of ordinary skill in the art would be able to discern which combinations of agents would be useful based on the particular characteristics of the drugs and the disease involved.

In one embodiment, the treatment method includes the co-administration of a compound disclosed herein or a pharmaceutically acceptable salt thereof and at least one cytotoxic agent. The term “cytotoxic agent” as used herein refers to a substance that inhibits or prevents a cellular function and/or causes cell death or destruction. Cytotoxic agents include, but are not limited to, radioactive isotopes (e.g., At²¹¹, I¹³¹, I¹²⁵, Y⁹⁰, Re¹⁸⁶, Re¹⁸⁸, Sm¹⁵³, Bi²¹², P³², Pb²¹² and radioactive isotopes of Lu); chemotherapeutic agents; growth inhibitory agents; enzymes and fragments thereof such as nucleolytic enzymes; and toxins such as small molecule toxins or enzymatically active toxins of bacterial, fungal, plant or animal origin, including fragments and/or variants thereof.

Exemplary cytotoxic agents can be selected from anti-microtubule agents, platinum coordination complexes, alkylating agents, antibiotic agents, topoisomerase II inhibitors, antimetabolites, topoisomerase I inhibitors, hormones and hormonal analogues, signal transduction pathway inhibitors, non-receptor tyrosine kinase angiogenesis inhibitors, immunotherapeutic agents, proapoptotic agents, inhibitors of LDH-A; inhibitors of fatty acid biosynthesis; cell cycle signalling inhibitors; HDAC inhibitors, proteasome inhibitors; and inhibitors of cancer metabolism.

The mixture was stirred at 25° C. for 2 hours and the volatiles were removed under reduced pressure to afford a residue that was redissolved in dichloromethane (10 mL) and treated with di-tert-butyl dicarbonate (5.87 mmol) and diisopropylethylamine (11.7 mmol). The reaction was stirred at room temperature for 24 hours, the insoluble materials were filtered off and the solvent removed under reduced pressure. Purification of this crude by preparative-TLC (65% ethyl acetate in hexanes) afforded the title compound as light yellow solid in 56% yield.

AA. Example 7 CAF Assay

This Example provides a protocol for assessing covalent adduct formation (CAF) between the compounds of the present application and KRAS.

In vitro covalent adduct formation assay: Covalent adduct formation (CAF) reactions between Cys12 of the KRAS 4B G12C protein and some of the compounds of Tables 1 to 4 were measured in vitro using liquid chromatography-mass spectrometry (LC-MS).

Recombinant Human KRAS 4B protein containing the G12C mutation was used in compound screening experiments. This protein contained 188 amino acids in total, including an N-terminal 6-Histidine tag, followed by a Tobacco Etch Virus (TEV) tag, followed by residues 1-169 of the native KRAS 4B sequence. The exact mass of the protein was 21,310 Da as determined by mass spectrometry. The full amino acid sequence is shown below:

The recombinant protein was expressed in E. coli BL21 cells and purified using affinity chromatography via a Ni-NTA column. Protein stocks were nucleotide-exchanged to >95% GDP, concentrated to 4 mg/mL, and stored at −80° C. in storage buffer (50 mM HEPES pH 7.4, 50 mM NaCl, 5 mM MgCl2, 1 mM DTT). Pure KRAS 4B G12C protein was diluted to a concentration of 5 μM in Tris Buffered Saline, pH 7.4. The compounds were dissolved in DMSO and added to the diluted protein to make a 10 μM concentration. The total DMSO concentration in the reaction was 4%. The reaction was mixed by pipetting and incubated at 22° C. for one hour. Aliquots of the reaction were taken over time and diluted 2:1 in 0.1% formic acid. The intact mass of the protein samples was measured by LC-MS using a QExactive+ mass spectrometer (Thermo Scientific). An amount of 500 ng total protein was injected onto a C8 reverse phase column, eluted with a seven-minute gradient of 30%-90% acetonitrile/0.1% formic acid, and analyzed for intact mass by the mass spectrometer. Adducts identified were confirmed to be within 1 Dalton of the expected mass, and the relative ratios of free:adduct protein were used to quantify the percentage of protein bound by the compound. CAF reactions were run in duplicate, with a typical variability of ±5%.
